The Negative Calorie Diet is unique in that it is conceived solely as a weight loss tool, and not as a tool for healthy living. Even with drastic food group elimination diets such as Atkins and The Zone, the creators tried to justify their theories by showing that overeating carbohydrates causes unhealthy metabolic changes in the body. They proposed that their diets were actually lifestyles, and could reduce the risk of diabetes, cancer etc. not just obesity.
The Negative Calorie Diet makes no such claims. It is designed for one purpose and one purpose only. The basic concept is not new, and is something that is generally accepted by nutrition experts everywhere. In order to lose weight, an individual must consume fewer calories than the body burns.
This causes the body to turn to its stores of fat and break these down in order to keep itself running, resulting in weight loss. Most of the diets that are accepted as being healthy and sustainable utilize this principle heavily, proposing substitutes to popular calorie-laden foods while maintaining the body’s healthy nutritional status.
Not so with the Negative Calorie Diet. In this incredibly restrictive version of things, the user must not simply consume few calories. They must consume negative calories. In other words, the number of calories going in must be less than the number of calories the body must use to digest the food, resulting in a net of nothing at all being eaten. Digestion has long been recognized as a long, slow process, and one that is extremely energy-consuming.
This is the reason why a large meal makes us feel sleepy. Chewing in itself requires considerable effort from the muscles of the jaw. When the food finally makes it to the stomach, blood rushes from the extremities to the lining of the gut in order to aid in digestion.
There are a great many calorie burning processes that must occur in order for food to be assimilated, and this diet takes advantage of that. Nothing can be eaten if the calories it provides are not completely negated by the body’s digestive action.

Good candidates for the diet are fibrous, water-dense foods that take a lot of chewing, are hard to swallow, suck up digestive fluids thereby making the eater feel satiated, and do not provide many calories to begin with. Examples are fibrous vegetables like celery and broccoli. At first glance, these are extremely nutritious foods and all is completely well with the world. Not so. As with most popular diets, the other basic food groups are almost, if not completely, eliminated. The body cannot survive long-term without proteins, fats and carbohydrates.
Even though one can eat as much as one likes of the allowed foods, the body is still starved. This is evident by the degree of weight loss promised by the diet two pounds per day. Experts agree that weight loss of such magnitude is not desirable, even dangerous.
When one also considers how nutritionally imbalanced this program is, it is easy to see why it is not recommended by any doctor anywhere in the world. Furthermore, it goes without saying that adhering strictly to the diet is a challenge for anyone who has ever had to force themselves to eat vegetables. In short, the Negative Calorie Diet is simply too much of a good thing. It takes the fundamentals of healthy weight loss and turns them into something dangerous.
